Managed vs. Unmanaged Code in .NET Development

In .NET development, the key difference between managed and unmanaged code lies in how memory and resources are handled by the runtime environment. The focus keyword for this topic is "managed code".

Managed Code: Managed code in .NET is executed by the Common Language Runtime (CLR), which provides automatic memory management, garbage collection, type safety, and exception handling. The code is compiled into an intermediate language (IL) that is then translated to machine code by the CLR at runtime. This ensures a more secure and stable execution environment.

Unmanaged Code: In contrast, unmanaged code does not run within the CLR and is typically written in languages like C or C++. It directly interacts with the system hardware and memory without the assistance of CLR services. This can result in greater performance but also raises concerns about memory leaks, security vulnerabilities, and stability issues.

When choosing between managed and unmanaged code in .NET development, it is essential to consider factors such as performance requirements, security considerations, and ease of maintenance. While managed code offers a safe and robust environment with CLR support, unmanaged code provides more fine-grained control over system resources.

Overall, understanding the difference between managed and unmanaged code is crucial for making informed decisions in .NET development projects.
